摘要
目的:研究血管内超声在冠脉复杂病变介入诊疗中的临床价值。方法:30例确诊为冠心病的患者,其中男性23例,女性7例,先采用冠脉造影(CAG),选择美国心脏病学会和美国心脏病协会(ACC/AHA)推荐的冠脉分型C型中弥漫性病变(>20mm)、近端血管过度扭曲病变,然后行IVUS检查,PCI术后再行IVUS检查,比较两者及PCI前后IVUS结果的差异。结果:CAG示支架贴壁良好,再行IVUS检查示支架贴壁不良率达78.4%,IVUS观察均达到支架置入理想标准。结论:IVUS在评价支架贴壁情况、选择高压球囊后扩张时,有着更明显的优势。
To assess the clinical application value of intravascular ultrasound in the complex coronary artery pathological change. Methods： A total of 30 CHD patients were recruited, complex coronary artery pathological change included in type 3 recommended by ACC/AHA were examined by CAG and IVUS. Minimal lumen area diameter and plaque burden at minimum area were detected and analyzed. Result： The results of before PCI and after PCI derived from IVUS were compared. 1VUS could fmd stent underexpension. Conclusion： 1VUS could guide the interventional therapy for complex coronary artery pathological change more efficiently. Post-dilation with high pressure guided by 1VUS can reduce the early rate of stent underexpension and attain a larger final stent CSA.
